Reactions between Ph3SnCl and the sodium salts of 5-mercapto-1-methyltetrazole (MTS-H), 2-mercaptobenzoxazole (MBZ-H), 2-mercaptobenzothiazole (MBT-H) and 2-mercapto-1-methylimidazole (MMI-H) gave Ph3Sn(MTS) (5: R=Ph, R′=Me), Ph3Sn(MBZ) 6, Ph3Sn(MBT) 7 and Ph3Sn(MMI) 8, respectively. Characterisation has been carried out for all compounds by IR, Moessbauer, 1H, 13C and 119Sn NMR spectroscopy as well as by X-ray crystallography for (5: R=Ph, R′=Me) and 6. Both (5: R=Ph, R′=Me) and 6, in the solid state, have cis-trigonal bipyramidal geometries due to intramolecular Sn-N(2) interactions. Moessbauer data for 7 was interpreted as indicating a similar cis-trigonal bipyramid geometry. The chelating ability of nitrogen-containing heteroarenethiolato groups, based on the strength of Sn-N inter-molecular bonds in Ph3SnS-heteroarenes, decreases in the sequence: pyridine-2-thiolato>pyrimidine-2-thiolato>1-methylimidazole-2- thiolato>benzoxazole-2-thiolato>1-methyltetrazole-5-thiolato>1- phenyltetrazole-5-thiolato. On dissolution, the Sn-N interactions in 5-8 undergo at least partial breakage. Elsevier Science Ltd.
